Hi,
This one has been driving me crazy all day. I have three
vectors, azimuth, frequency and power, which I would like
to histogram and plot on a polar axis. I can plot a
scatter plot this way no problem but the histogram gets
messed up somehow. An example is below, anybody know how
to do this properly??
import random
import numpy as np
import matplotlib.pyplot as plt
baz = np.zeros((20))
freq = np.zeros((20))
pwr = np.zeros((20))
for x in range(20):
baz[x] = random.randint(20,25)*10
freq[x] = random.randint(1,10)*10
pwr[x] = random.randint(-10,-1)*10
baz = baz*np.pi/180.
abins = np.linspace(0,2*np.pi,360)
sbins = np.linspace(1, 100)
H, xedges, yedges = np.histogram2d(baz, freq,
bins=(abins,sbins), weights=pwr)
plt.figure(figsize=(14,14))
plt.subplot(111, polar=True)
#plt.scatter(baz, freq, c=pwr)
plt.pcolormesh(H)
plt.show()
